Description

Technical Field

[0001] This utility model relates to the field of battery installation technology, and in particular to a battery installation structure for outdoor photovoltaic capacity expansion. Background Technology

[0002] Currently used outdoor photovoltaic energy storage equipment mainly consists of battery containers. A battery container is a highly integrated, standardized energy storage system. It pre-assembles battery modules, management units, temperature control, and fire suppression systems within a robust enclosure, forming a rapidly deployable, plug-and-play unit. Its design effectively withstands harsh outdoor environments, and its internal temperature control system ensures the batteries operate at optimal conditions, thereby extending their lifespan and improving safety. This integrated solution significantly simplifies on-site installation, reduces construction and maintenance costs, and is an ideal choice for large-scale photovoltaic energy storage.

[0003] Currently used battery containers are installed on solid concrete foundations within power plant areas. However, with the increasing number of outdoor photovoltaic (PV) panels installed, the power generation from PV also increases. To rationally allocate the storage and use of PV power, capacity expansion for outdoor PV systems is urgently needed. Therefore, this paper proposes a battery installation structure for outdoor PV capacity expansion, designed to quickly achieve capacity expansion of outdoor PV systems without requiring modification of existing battery containers, while occupying a relatively small area of ​​the plant site. Utility Model Content

[0004] This utility model provides a battery mounting structure for outdoor photovoltaic capacity expansion, which is used to install prefabricated or standard battery containers in a three-dimensional manner without modifying the battery container, and the installation operation is convenient.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An outdoor photovoltaic capacity expansion battery mounting structure includes at least two battery containers installed in a three-dimensional alignment. Each battery container has a door on its long side and corner fittings at each of its four corners. Each corner fitting has an elongated lock hole on three outer sides. A connecting assembly connects adjacent battery containers. The connecting assembly includes four support blocks, each support block having a locking rod that moves along its length. Both ends of the locking rod have locking blocks that mate with the lock holes. Guide grooves are formed on the side walls of the support blocks at a predetermined angle, and a swing rod is installed within the guide grooves. The swing rod is connected to the locking rod; rotating the swing rod causes the locking blocks to rotate via the locking rod, aligning the locking blocks with the lock holes for unlocking, or offsetting them to lock. Two support blocks on either side of the door of the battery container are connected to square tubes. Two square tubes are detachably connected to a footrest. The footrest is located in front of the door of the battery container and is used to support workers standing and operating the battery containers.

[0007] Furthermore, there are two battery containers, with the lower battery container installed on a concrete foundation.

[0008] Furthermore, the footrest workbench includes two square tubes detachably connected to two square tubes 1 respectively. A drain plate is connected between the square tubes 2. A vertical tube 1 is provided on the side of the square tube 1 near the battery container. A vertical tube 2 is provided on the side of the drain plate away from the battery container. An L-shaped tube is connected between the top ends of the vertical tube 1 and the vertical tube 2. The L-shaped tube is arranged along the outer edge of the drain plate. The two vertical tubes 2 form an inlet and outlet.

[0009] Furthermore, one of the vertical tubes is provided with an upward-facing locking frame on its upper side, and the other vertical tube is provided with a railing on its upper side. By swinging the railing toward the locking frame, the railing can be placed across the entrance and exit and locked into the locking frame.

[0010] Furthermore, the drain plate has folded edges on both sides, near and away from the battery container.

[0011] Furthermore, both square tube one and square tube two are provided with elongated holes. Square tube two is movably inserted into square tube one. After the elongated holes on both are aligned, they can be locked together using bolts and nuts.

[0012] Furthermore, the top of the uppermost battery container is connected to a photovoltaic panel assembly via a connecting component. The photovoltaic panel assembly includes a support frame for installing the photovoltaic panel. Support tubes are provided at the four corners of the support frame, and the bottom wall of the support tubes is also provided with locking holes that are the same as and aligned with the corner pieces.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] I. Meet the requirements for factory site occupation and renovation

[0015] Smaller factory footprint: By aligning and installing multiple battery containers vertically, vertical space is fully utilized. Compared with the traditional planar layout, the floor area occupied by the factory is greatly reduced. More battery containers can be installed in the limited factory space to meet the space requirements for outdoor photovoltaic capacity expansion.

[0016] No modification required for the battery container: This structure directly utilizes the standard battery container, adding an additional design to its original structure. No modification is required to the battery container itself. Only other simple connecting parts and footrests and workbenches need to be processed. This saves modification costs, avoids potential safety hazards and performance impacts caused by modification, and shortens the project implementation cycle.

[0017] II. Convenient and efficient installation

[0018] Quick Installation and Locking: Adjacent battery containers are connected using a connecting assembly. By rotating a lever, the locking lever and locking block rotate, aligning or misaligning the locking holes, thus enabling quick unlocking and locking of the battery containers. This connection method is simple to operate, requiring no complicated tools or professional skills, greatly improving the efficiency of installation work and enabling rapid installation and capacity expansion of outdoor solar power systems.

[0019] The footrest is easy to assemble and disassemble: The footrest is connected to square tube 1 in a detachable manner. Square tube 1 and square tube 2 are provided with elongated holes. By inserting square tube 2 into square tube 1 and aligning it with the elongated holes, the connection is locked with bolts and nuts. Its structure is sturdy and also facilitates the installation and disassembly of the footrest.

[0020] Independent heat dissipation: Four support blocks are vertically placed between the two battery containers, opening up the two adjacent battery containers and increasing the air circulation space between them. This facilitates independent heat dissipation for the two battery containers, improving the service life and performance stability of the batteries. Attached Figure Description

[0030] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0031] See Figures 1 to 8 This utility model provides a battery installation structure for outdoor photovoltaic capacity expansion, including two battery containers 1 installed in a three-dimensional alignment, with the lower battery container 1 installed on a concrete foundation. This embodiment only provides a specific installation scheme for two battery containers 1, but based on the extension of this embodiment, multiple battery containers 1 can also be installed three-dimensionally according to specific circumstances, and multiple installation schemes should also fall within the reasonable disclosure scope of this utility model.

[0032] The battery container 1 has an opening mechanism on its long side (front side), which is mainly for staff to open the battery container 1 to operate inside.

[0033] Each of the four corners of the battery container 1 has a corner fitting 101, which are standard parts. Each of the three outer surfaces of the corner fitting 101 has an elongated locking hole 8. A connecting assembly connects two adjacent battery containers 1. The connecting assembly includes four hollow tubular support blocks 5, which vertically support the two battery containers 1, allowing them to be separated and facilitating independent heat dissipation. A locking rod 9 is movably inserted through the support block 5 along its length.

[0034] Both ends of the locking rod 9 extend beyond the support block 5 and are fixedly welded to the locking block 7. The locking block 7 is adapted to the lock hole 8. The locking block 7 is also an oblong structure. In order for the locking block 7 to pass through the lock hole 8 and enter the corner piece 101, the locking block 7 needs to be set slightly smaller than the lock hole 8, but the length of the locking block 7 should be greater than the width of the lock hole 8 to achieve locking. A 90-degree guide groove 10 is opened on the side wall of the support block 5, and a swing rod 6 is arranged horizontally in the guide groove 10. The inner end of the swing rod 6 is welded to the locking rod 9, and its outer end extends to the outside of the guide groove 10. The two support blocks 5 on both sides of the opening of the battery container 1 are fixedly connected to the square tube 13. That is, the two support blocks 5 on the left are welded to the square tube 13 on the left, and the two support blocks 5 on the right are welded to the square tube 13 on the right. Two square tubes 13 are detachably connected to a footrest work platform, which is located in front of the door of the battery container 1 and is used to support the staff to stand and work on the battery container 1.

[0035] The installation steps for the battery container 1 are as follows: By hoisting two square tubes 13, place the two support blocks 5 on both sides onto the four corner pieces 101 at the top of the lower battery container 1. Beforehand, rotate the swing arm 6. The swing arm 6, through the locking rod 9, drives the locking block 7 to rotate, aligning the locking block 7 with the locking hole 8. This allows the lower locking block 7 to insert into the locking hole 8 of the lower corner piece 101. At this time, the upper locking block 7 aligns with the locking hole 8 of the lower corner piece 101 of the pre-installed battery container 1. Hoist the pre-installed battery container 1, allowing the locking hole 8 of the lower corner piece 101 of the battery container 1 to fit onto the upper locking block 7, inserting the upper locking block 7 into the upper corner piece 101. Then rotate the swing arm 6 ninety degrees to displace the locking block 7 from the locking hole 8, thus locking the two battery containers 1 on the upper and lower layers. Finally, install the footrest workbench onto the two square tubes 13 by hoisting.

[0036] Specifically, the footrest includes two square tubes 12 that are detachably connected to two square tubes 13. A drain plate 16 is connected between the square tubes 12. The left and right sides of the drain plate 16 are welded to the two square tubes 12 respectively. The drain plate 16 has multiple drainage holes arranged in an array to prevent water accumulation and slipping. A vertical tube 20 is vertically welded to the side of the square tube 13 that is close to the battery container 1. A vertical tube 19 is welded to the side of the drain plate 16 that is away from the battery container 1. An L-shaped tube 15 is welded between the top of the vertical tubes 20 and 19. The L-shaped tube 15 is arranged along the outer edge of the drain plate 16. The two vertical tubes 19 form an inlet and outlet 14.

[0037] When it is necessary to work on the upper battery container 1, the staff can climb the ladder or other means to reach the foot platform, and enter through the entrance 14 and stand on the drain floor 16 on the front side of the battery container 1, which facilitates the work on the upper battery container 1. The L-shaped tube 15 is set to prevent falls.

[0038] Specifically, a locking frame 18 with an upward opening is welded to the upper side of the left vertical tube 2 19, and a railing 17 is rotatably installed on the upper side of the right vertical tube 2 19. By swinging the railing 17 towards the locking frame 18, the railing 17 can be placed across the entrance / exit 14 and locked into the locking frame 18, which can prevent workers from falling from the entrance / exit 14 when working on the foot platform, thus improving work safety.

[0039] Specifically, the drain base plate 16 has folded edges on both sides near and away from the battery container 1, which can increase the overall structural strength of the drain base plate 16, prevent excessive deformation when workers step on it, and ensure the stability and reliability of the footrest workbench.

[0040] Specifically, both square tube 13 and square tube 2 are provided with elongated holes 11. Square tube 2 is movably inserted into square tube 13. After the elongated holes 11 on both are aligned, they can be locked together by using bolts and nuts, which facilitates the assembly and disassembly of square tube 13 and square tube 2.

[0041] Specifically, the top of the uppermost battery container 1 is connected to a photovoltaic panel assembly via a connecting component, which can make full use of the three-dimensional space to install photovoltaic power generation and reduce sunlight exposure to the battery container 1. The photovoltaic panel assembly includes a support frame 3 for installing the photovoltaic panel 2. Support tubes 4 are welded at the four corners of the support frame 3. The bottom wall of the support tube 4 is also provided with lock holes 8 that are the same as and aligned with the corner piece 101.

[0042] The installation steps for the photovoltaic panel module are as follows: Place the four support blocks 5 on the four corner pieces 101 on the top of the uppermost battery container 1, and rotate the swing rod 6 in advance. The swing rod 6 drives the locking block 7 to rotate through the locking rod 9, so that the locking block 7 is aligned with the locking hole 8, so that the lower locking block 7 can be inserted into the locking hole 8 of the lower corner piece 101. At this time, the upper locking block 7 is aligned with the locking hole 8 on the support tube 4. By hoisting the photovoltaic panel module, the four locking holes 8 on the support tube 4 are fitted into the four upper locking blocks 7. Then rotate the swing rod 6 ninety degrees to make the locking block 7 and the locking hole 8 misaligned to lock the photovoltaic panel module.

[0043] The advantages of rapid assembly and disassembly of photovoltaic (PV) panels include: Since the PV panels use the same interlocking connection method as the battery container 1, installation and disassembly are convenient and quick. In the event of severe weather such as strong typhoons, the PV panels can be quickly removed, preventing damage and reducing economic losses. Furthermore, since a single battery container 1 typically weighs over 5 tons, its weight and stable installation mean that, in typical typhoon conditions, it is usually unnecessary to disassemble the upper layers of the container in a three-story rack system (up to four stories). Even in special circumstances requiring disassembly, the process is relatively convenient.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
